HOISTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 727,442, dated. May 5, 1903.

Application filed January 18, 1903. Serial No. 139,304. (No model.)

To all whom it may concern.-

Be it known that I, MICHAEL RATH, a citizen of the United States, and a resident of Two Rivers, in the county of Manitowoc and State of Wisconsin, have invented a new and Improved Hoisting Device, of which the following is a full, clear, and exact description.

This invention relates to improvements in hoisting devices or elevators, particularly adapted for the use of builders in raising brick and other building material to the place of work, the object being to provide a hoisting device that may be readily placed in po sition and adjusted as to height as the building progresses.

I will describe a hoisting device embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a hoisting device embodying my invention. Fig. 2 is a plan view thereof. Fig. 3 is a detail plan showing the wheelbarrow-guide mechanism employed. Fig. 4 is a side view thereof, and Fig. 5 is a diagrammatic view illustrating the general arrangement of the hoisting rope or cable.

Referring to the drawings, 1 designates a mast or standard designed to be erected at either the outer or inner side of a buildingwall, and it is held in place by means of bars 2, secured to the mast or standard and also secured, by means of bolts or otherwise, to the floor-timbers of the building. v This mast or standard preferably consists of tubular metal and is made in separable sections, so that the hoisting device may be raised as the wall is built upward. Mounted to swing on the mast are divergent arms 3 4:, the inner ends of the arms being connected, asclearly shown in Fig.2. Brace-rods 5 connect the arms 3 4 with an upper collar 6, mounted to rotate on the mast, and downwardly and inwardly extended brace-rods 7 connect the said arms with a lower collar 8. This collar 8 rests on a collar 9, adjustably secured to the mast by means of a set-bolt or the like. A hoisting rope or cable 10 passes around a pulley 11, attached to an anchoring device or stake 12,

and then around a double pulley 13 at the lower end of the mast, and then around pulleys 14 and 15 at the inner ends of the arms 3 4E, and then over pulleys 16 17 at the outer ends of the arms. The ends of the rope or cable are designed to be connected to wheelbarrows or other devices to be lifted.

I have here shown the ends connected to wheelbarrows 16 17 by means of chains 18, having connection with the handles of the wheelbarrows and also with the wheels there of. As a means for guiding a wheelbarrow in its upward movement I provide a guidecable 19. This guide-cable extends from a foot-plate 20 at the lower end of the mast and thence over a cross-head 21, adjustably connected to the mast, so it may be raised or lowered, as occasion may require. Connected to a handle of each wheelbarrow is a device for engaging the guide-cable. The device consists of two jaws 22 23, pivoted to the handle and having their upper edges beveled or made cam shape.

In the operation a horse or other draft animal is hitched to the rope or cable 10, as shown in Fig. 1. As the'horse moves forward or toward the building one wheelbarrow, with its load, will be raised, while the other empty wheelbarrow is lowered. When the load reaches the top, the arms may be swung to place the barrow on a platform or the like on the building. As the wheelbarrow is raised the cam portions of the jaws 22 23 will come in contact with the cross-head 21 and be opened, thus automatically releasing the barrow from the guide-cable. When the movement of the rope or cable 10 is reversed, of course the horse must be turned around to draw in the opposite direction.

The collars 6 and 8 have two-part bushings 6, which when removed will permit said collars to pass over connecting-joints of the mast when the device is raised, and after raising the arms the bushings are to be again inserted.

Adjustable on the mast are arms 24, from which brace cables 25 extend to suitable anchors.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A hoisting device comprising a mast, divergent arms mounted to swing on said mast and adjustable vertically thereon, pulleys at the inner ends of said arms, pulleys at the outer ends of said arms, pulleys at the lower end of the mast, an anchoring device, a pulley attached to said anchoring device, and a hoisting rope or cable extending over the several pulleys.

2. A hoisting device comprising a mast, divergent arms mounted to swing on said mast, pulleys at the inner ends of said arms, pulleys at the outer ends of said arms, pulleys at the lower end of the mast, an anchoring device, a pulley attached to said anchoring device, a a cable extending around the several pulleys, and a guide for the load to be lifted.

3. A hoisting device comprising a mast, arms mounted to swing on said mast, pulleys at the inner ends of said arms, pulleys at the .outer ends of said arms, pulleys at the lower end of the mast, a hoisting rope or cable extending around said several pulleys, a crosshead adjustably connected to the mast, and a guide-cable extended from the lower portion of the mast to said cross-head at opposite sides of the mast.

4. In ahoisting device, a mast, arms mounted to swing on said mast, a hoisting-rope, wheelbarrows or the like adapted for connection with the hoisting-rope, a guide-cable connected to the mast, and jaws connected to the wheelbarrows or the like for engaging With said guide-cable.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MICHAEL RATII.
